Mitigation Of Liquefaction And Associated Ground

Mitigation Of Liquefaction And Associated Ground

The risk of liquefaction and associated ground deformation can be reduced by various groundimprovement methods including densification, solidification (e.g., cementation), and gravel drains or stone columns. use of gravel drains is a rather recent development compared with the more traditional soil densification approaches (ina, 2001).

Liquefaction is a hazardous seismicbased phenomenon, which causes an abrupt decrease in soil strength properties and can result in the massive destruction of the built environment. this research presents a novel approach to reduce the risk of soil liquefaction using jetgrouted micropiles in clean sands. the saturated soil profile of the study project mainly contains clean sands, which are suitable to more reliably employ simplified soil liquefaction.
